Semi-Final on Stars HU 256 man shootout Q

Ok... I want you to put hero and villian on a hand because i think it will help me as the hand is bizzare and i can talk more once some of you give your opinion.....So it's the stars HU shootout and its my seventh game now as its down to the semi-finals now so obviously the guy i'm playing I assume is pretty decent if he's won 6 in a row and my only real read....

3rd hand in theres been my raise on the button and a fold my villian and villian raise on the button and a fold by me... Next hand I get XX and raise the button and he calls... (mind you first level and no reads) Flop comes 974 rainbow, and he checks i bet pot which is 120, and he min raises to 240, and I call. Turn in a 10, and theres 600 in the pot now. He bets 240, and i raise to 540, villian calls. River is a Q, and he checks and I shove my remaining chips in the middle, and he tanks and calls with XX.

Please put me and my opponent on a hand, as I find the result to blow me away. Ty guys... Many responses would be greatly helpful and appreciated.

Hero has a straight or good two pair. Villain has 98 cause he's a donk.

I am so thankful you said that ISF, because truth his hero had air, ak. But the I had him on exactly that 98 or some dumb pair or nothing with his donk check reraise on the flop. So the ten seemed like a fantastic card to rep, so i made the small reraise on the turn, because that seems strong to me, and i shoved the river and he calls me with 37! And I'm lost now because he absolutly made a good call but in my opinion was terrible. I mean I suppose my play was bad, but as you said It looked straightish or strong two pair... So my question is, is this a horrible play? My opponents play? With no reads, how should the hand have been played... Thanks man.

you both played bad! normally this is a pretty bad spot to bluff a donk
